I'd advise buying all the light you can afford- you can do two really nice plants under the 400, if you just let them veg for an extra two weeks.

I think most of us have found that we outgrow gear pretty quick, and a lot of us have a small light or two kicking around that we don't use anymore.

It's like buying clothes for a kid- you buy on the edge of being too big, cause it'll be too small soon enough...

The hps will be fine for veg- your structure won't be as tight as it could be, but it'll be fine. If you want both, digi's are cool, and getting much cheaper... the switchable magnetic will be about $25US more than the hps in whatever wattage, and then the cost of the extra bulb, which should be about $100- no sense spending extra on the ballast so that you can run a crap bulb.

So yeah- I'd go 400hps, 400digi if I were feeling sassy...
